AGN 193109 is primarily used in scientific research to study the mechanisms of retinoid signaling pathways. It acts as a potent antagonist of retinoic acid receptors (RARs), making it a valuable tool in understanding the role of retinoids in cellular processes such as differentiation, proliferation, and apoptosis. Researchers utilize AGN 193109 to investigate its effects on gene expression and its potential implications in diseases like cancer, where retinoid signaling is often dysregulated. Additionally, it is employed in developmental biology studies to explore the impact of disrupted retinoid pathways on embryonic development. Its application extends to pharmacological studies aimed at developing targeted therapies for conditions influenced by retinoid receptor activity.
